BillD22 Posted October 3, 2020 Share Posted October 3, 2020 (edited) In this series our FS2020 default B747-8i has just levelled off at our initial cruise altitude of FL360 and accelerated to Mach .8 en route from Dulles International Airport outside Washington DC (KIAD) to Heathrow Airport in London UK (EGLL). The aircraft is over Portsmouth, New Hampshire (KPSM) heading towards Portland, Maine (KPWM). FS2020 weather parameters are the imported RW conditions. In this shot the upper left map insert shows the aircraft position and the lower right winds aloft insert shows the forecast winds at flight level. The forecast is 120 knot tailwind over Portland. Not much to see out the window with a cloud deck below us but check out the ND wind and groundspeed readout in the next shot. . We're showing a 20 degree offset tailwind giving us a slightly lower than forecast 109 knot tailwind but resulting in a 606 knot (697 mph) groundspeed! Wow! If this holds up for a while we'll be getting into Heathrow a little early. Fortunately we're not going the other way! :D Edited October 3, 2020 by BillD22 Link to comment Share on other sites More sharing options...
DAVIDSTRAKA Posted October 3, 2020 Share Posted October 3, 2020 Definitely some groundspeed help there!

NMLW Posted October 3, 2020 Share Posted October 3, 2020 Nice bit of luck with the tail wind Bill, but you've got to make the return flight sometime - just check the weather first. :D Larry Link to comment Share on other sites More sharing options...
dbauder Posted October 3, 2020 Share Posted October 3, 2020 Don't worry, given those winds, you won't be flying the same route back. You'll be further north, out of the jetstream. If you were to fly LHR- SEA, or YVR or even ANC, you would probably get to see what Greenland looks like in the new sim! Link to comment Share on other sites More sharing options...
